Team at Nagoya University develops „ClearSee“ technology to render plant material transparent

The technology is based on the removal of chlorophyll by a chemical reagent. After irradiation with fluorescent light, It allows to visualize tagged plant structures such as proteins, pollen tubes etc. by a confocal microscope once these structures have been tagged by dyes or by coexpression of fluorescent proteins such as GFP.

Toyota Motor close to commercialize yeast-based bioethanol based on Napier grass as a drop-in fuel.

Process development has reached a 46 kL stage with 90 % yields based on biomass sugar content. Biomass hydrolysis is done by dilute sulfuric acid. The Napier grass is from Indonesia, and the yeast was engineered to utilize both glucose and xylase, by activating the pentose phosphate cycle and cloning a xylose isomerase from termites […]

Artificial blood vessels built from vascular endothelial and smooth muscle cells using cell-selective adhesion peptides bound to fibroin: Nagoya University

The group of Ryuji KATO at Nagoya University is using collagen vitrogel deposited on sericin to bind vascular endothelial and smooth muscle cells selectively. Preliminary animal experiments indicate that intima thickening and thrombus formation can be prevented in such grafts. Japanese Society for Biotechnology Annual Meeting, Kagoshima, October 27, 2015, Poster 1P-223

RIKEN team develops method to expand pluripotent hematopoietic progenitor cells

By inhibiting the transcription factor E2A by an inhibitory protein Id3, introduced in mice using a retroviral vector, the group of Hiroshi KAWAMOTO succeeded to expand blood hematopoietic stem cells very significantly. The findings are considered highly significant for possible artificial amplification of multipotent hematopoietic progenitor cells. RIKEN news release, October 23, 2015

DNA Chip Research Co. will start service for quality assessment of mesenchymal stem cells, Taiyo Nippon Sanso offers complete cryopreservation service

The Kanagawa-based company (which will move to Tokyo from Nov. 1) has announced to start service and sales for quality control of mesenchymal stem cells. The “C3 check service” is based on comparative genomic hybridization (CGH). This will be done in collaboration with ZenoAQ, a leading company for animal health products, which offers a cryopreservation […]

Cell Bank of Japan will expand business beyond autologous cultured dermal fibroblast cells

The Tokyo-based private company, which has permission since 2014 to prepare in their cell culture processing facilities autologous cultured dermal fibroblast cells for cosmetic purposes, plans to expand her business and apply her know-how to prepare a variety of cells for clinical trials at academia and in pharmaceutical companies. Nikkei Biotech news release, October 16, […]
